Everstein

Everstein was a county in the Weser hills, whose counts moved to Polle after the Welfs forced them to sell Everstein Castle in 1284. Around 1335 they were forced to surrender Ohsen Castle to Brunswick-Lüneburg.

After Count Hermann VII's only son died, he made an inheritance treaty with Lippe. The Welfs overrode it in the Everstein succession feud of 1405 to 1407, and in 1408 the county and Polle Castle passed to Brunswick-Lüneburg. The family's Pomeranian branch, Eberstein-Naugard, survived until 1663.
